I duplicated the image and put one the images in Grayscale, then put it back on RGB mode. I wanted to give this wallpaper a soft and pink style, but I played a bit the the colour balance to gain this pink-like theme.The second copy of the image, I distorted it by putting using the filter "Diffuse Glow" in the Distort sections among filters and exaggerated in it.I put those two images as layers on a 1280x960 blank sheet, decreased the opacity of the pink-theme picture and there you go.Tp put the finishing touch, I traced a feature picture and put the letters "HL" on it for "Haruna & Lala".
